# United States Space Command

United States Space Command (USSPACECOM or SPACECOM) is a unified combatant command of the United States Department of Defense, responsible for military operations in outer space, specifically all operations 100 kilometers (62 miles) and greater above mean sea level. U.S. Space Command is responsible for the operational employment of space forces that are provided by the uniformed services of the Department of Defense.
Space Command was originally created in September 1985 to provide joint command and control for all military forces in outer space and coordinate with the other combatant commands. SPACECOM was disestablished in 2002, and its responsibilities and forces were merged into United States Strategic Command. It was reestablished on 29 August 2019, with a reemphasized focus on space as a warfighting domain.
The U.S. Space Force is the military service responsible for organizing, training, and equipping the majority of forces for U.S. Space Command, which also includes a smaller number of forces from each of the other branches of the U.S. Armed Forces.

## Mission

U.S. Space Command, working with allies and partners, plans, executes, and integrates military spacepower into multi-domain global operations in order to deter aggression, defend national interests, and when necessary, defeat threats.
U.S. Space Command has four "space truths" that provide the foundation for its vision and operations:
* Space is a vital interest that is integral to the American way of life and national security.
* Space superiority enables the Joint Force to rapidly transition from competition to conflict and prevail in a global, all-domain fight.
* Space warfighters generate the combat power to win in space.
* Space provides the warfighter a combat advantage from the ultimate high ground to the last tactical mile.

## History
### Early military space defense

Early military space activities were predominantly focused on research and development, rather than operations, and split across the Air Force, Army, and Navy. In 1959, Admiral Arleigh Burke proposed the creation of the Defense Astronautical Agency to control all military space programs. This proposal was supported by the Army and Navy, but opposed by the Air Force.
Arguing that space defense was an extension of air defense, the Joint Chiefs of Staff ultimately agreed with the Air Force, putting operational control of space defense forces under the unified Continental Air Defense Command and multinational North American Air Defense Command in 1960. In 1975, Continental Air Defense Command was inactivated and replaced with Aerospace Defense Command (ADCOM), a specified command led by the Air Force. In 1981, North American Air Defense Command changed its name to North American Aerospace Defense Command to better reflect its role in both air and space defense.

| | Fourteenth Air Force | Vandenberg Air Force Base, California | 23 March 1992 – 1 October 2002 |
The Reagan Administration's Strategic Defense Initiative brought a new focus on space. In 1983, General James V. Hartinger, the commander of Aerospace Defense Command and Air Force Space Command, proposed movement towards a unified space command. The Air Force supported a unified command, which would be dominated by the aerospace service, however, the Army, Navy, and Marine Corps were satisfied with the current arrangement. However, the White House supported the Air Force's position that a unified command should be created, and on 20 November 1984, President Ronald Reagan approved its establishment. U.S. Space Command's missions would include integrating tactical warning and space operations, including control of space, direction of space support activities, and planning for ballistic missile defense. U.S. Space Command would also replace Aerospace Defense Command as the supporting U.S. command to North American Aerospace Defense Command, sharing the same commander.
On 23 September 1985, U.S. Space Command was activated as a functional combatant command at Peterson Air Force Base, Colorado Springs and Aerospace Defense Command was inactivated on 19 December 1986. In February 1988, U.S. Space Command was assigned the ballistic missile defense mission in preparation for assuming operational command of the Strategic Defense Initiative. However, the end of the Cold War significantly reduced the investment in SDI.
In 1991, the Joint Chiefs of Staff debated establishing U.S. Strategic Command assume responsibility for nuclear deterrence, missile defense, and space. U.S. Space Command would have been made a sub-unified command under the U.S. Strategic Command. However, the decisive role played by U.S. Space Command in the Persian Gulf War prevented its absorption into U.S. Strategic Command, providing tactical missile warning, GPS, and other space data to forces in theater.
In 1997, General Howell M. Estes III proposed designating space as a geographic area of responsibility, transitioning U.S. Space Command from a functional to a geographic command. This effort was opposed by the Joint Staff, the State Department, and the National Security Council and did not occur. However, there was growing discussion about giving U.S. Space Command the mission for information support and renaming it to United States Space and Information Command. While U.S. Space Command was not renamed, it did assume responsibility for information, or cyberspace, operations.
Following the September 11 attacks, there was a growing focus on homeland defense and counter-terrorism at the expense of space. The Defense Department was intent on establishing United States Northern Command, merging U.S. Space Command and U.S. Strategic Command in 2002. On 1 October 2002, the first U.S. Space Command was shut down.

### Space in U.S. Strategic Command

On 1 October 2002, as U.S. Space Command inactivated, a new U.S. Strategic Command at Offutt Air Force Base, Nebraska, stood up. Within STRATCOM, the responsibilities for space operations were initially managed by the Joint Functional Component Command for Space and Global Strike, led by the commander of the Air Force's Eighth Air Force. However, in 2006, space regained its own functional component under U.S. Strategic Command, under the command of the Fourteenth Air Force commanded.
Following the inactivation of U.S. Space Command in 2002, Russia and China began developing sophisticated on-orbit capabilities and an array of counter-space weapons. In particular, China conducted the 2007 Chinese anti-satellite missile test, destroying its Fengyun spacecraft, which, according to NASA, created 2,841 high-velocity debris items, a larger amount of dangerous space junk than any other space event in history. In 2008, U.S. Strategic Command conducted Operation Burnt Frost to destroy a non-functioning National Reconnaissance Office satellite, before its toxic hydrazine tank could reenter and cause potential harm to human safety, with a RIM-161 Standard Missile 3 launched from the USS Lake Erie.
This construct lasted until 2017, when the commander of Air Force Space Command became the Joint Force Space Component Commander, replacing it.

### U.S. Space Command reestablished

The 2019 National Defense Authorization Act, which was signed into law in 2018, directed the re-establishment of U.S. Space Command as a sub-unified combatant command under U.S. Strategic Command; however, in December 2018, the Trump administration directed that U.S. Space Command instead be a newly established, full unified combatant command, with full responsibilities for space.
On March 26, 2019, U.S. Air Force General John Raymond was nominated to be the commander of the second establishment of USSPACECOM, pending Senate approval. In 2019 the Department of the Air Force released the list of finalists for the location of Headquarters Space Command: Cheyenne Mountain Air Force Station, Schriever Air Force Base, Peterson Air Force Base, Buckley Air Force Base, Vandenberg Air Force Base, and Redstone Arsenal. U.S. Space Command was officially reestablished as a geographic combatant command on August 29, 2019, during a ceremony at the White House. The former Joint Force Space Component Commander was dissolved and folded into Space Command. Following the creation of the United States Space Force in December 2019, the Department of the Air Force widened its search for a location of Space Command's permanent headquarters.
USSPACECOM has two subordinate commands: Combined Force Space Component Command (CFSCC), and Joint Task Force Space Defense (JTF-SD). CFSCC plans, integrates, conducts, and assesses global space operations in order to deliver combat relevant space capabilities to Combatant Commanders, Coalition partners, the Joint Force, and the Nation. JTF-SD conducts, in unified action with mission partners, space superiority operations to deter aggression, defend U.S. and allied interests, and defeat adversaries throughout the continuum of conflict.
In August 2020, In the meeting of the National Space Council, acting Director of National Intelligence announced ''in case of an attack on the U.S. satellites the operational control of intelligence community assets will be in the ambit of the military'', resulting in the National Reconnaissance Office being operationally subordinated to the commander of U.S. Space Command in matters of space defense.
On 24 August 2021, two years after its establishment, U.S. Space Command announced that it had reached initial operating capability. Achieving full operating capability, according to Lieutenant General John E. Shaw, deputy commander of U.S. Space Command, is dependent on the selection of the combatant command's permanent headquarters.
U.S. Space Command is planning to reorganize its subordinate commands, possibly reactivating the Joint Force Space Component Command (JFSCC), the precursor organization of the combatant command. JFSSC is planned to be the combatant command's "primary warfighting command," formed by combining CFSCC and JTF–SD. Space Force Lieutenant General Stephen Whiting, commander of SpOC, is planned to lead the new organization.
In 2023, U.S. Space Command regained its responsibility for missile defense from U.S. Strategic Command and will be taking over the Joint Functional Component Command for Integrated Missile Defense.

#### Headquarters

In January 2021, it was announced that Redstone Arsenal in Huntsville, Alabama was the preferred final location for U.S. Space Command. The other locations in contention were Kirtland Air Force Base, Offutt Air Force Base, Joint Base San Antonio, its interim location at Peterson Space Force Base, and Patrick Space Force Base. Despite Peterson Space Force Base in Colorado, being both the original and interim location of Space Command headquarters, Redstone Arsenal was selected, reportedly due to political pressure directly from then-president Donald Trump. A formal review from the DoD IG was initiated to ensure the process that selected Huntsville as the preferred location was impartial and factually sound. Former Secretary of Defense Lloyd Austin came out with his public support and backed the Department of the Air Force's decision process which resulted in the selection of Redstone Arsenal. In May 2022, the review found that the selection of Redstone Arsenal as the permanent site was reasonable and justified. In July 2023, the move to Huntsville was cancelled. Gen. James Dickinson, Commander of the Space Command, argued that moving the headquarters to Alabama from its current location in Colorado Springs would hurt military readiness. Republicans have accused the Biden administration of acting out of spite due to a partisan standoff over the Pentagon's abortion access policies at the time.

Previous, now-deactivated functional components included the Combined Force Space Component Command at Vandenberg Space Force Base, California, and the Joint Task Force–Space Defense at Schriever Space Force Base, Colorado. Both were disestablished with the creation of U.S. Space Forces – Space to take on SpOC's Space Force responsibilities.

### Relationship with the United States Space Force

United States Space Command is the unified combatant command for all military space operations, while the United States Space Force is the military service responsible for organizing, training, and equipping the majority of forces for U.S. Space Command. Space Command's Space Force service component is Space Operations Command, providing the majority of space forces. U.S. Space Command also consists of smaller amounts of forces from the United States Army, United States Marine Corps, United States Navy, and United States Air Force. This mirrors the relationship between the Space Force's predecessor, Air Force Space Command, and U.S. Space Command (and between 2002 and 2019, United States Strategic Command).
